Be it knowntht I,- Ro'enn'r F; HUME, a citizen of the United States, residing at Lixna,in` the count of Allen and State of Ohio, have invente' certain useful Improvements in Irlc-:ubatbrsgt of which the following is a specification', reference A being had there; 1n to the accompanying drawingij -f A The invention relates to an incubator, and has for its primary' object to provide an apparatus of'thisfcharacter wherein the use of a lam orburner interiorly thereof is entirely e iminated, thereby avoiding conL ag'ration, yet the requiredl heat for the hatching of eggsy will ,bejhad toassure the successful operation of the apparatus.

Andtherbbject 'of' the invention is the provision oan apparatus: of thisV character wherein the construction thereof is' novelfin form's'o-that' boilingv Waterl can be introduced therein, which vwill serve as `the heating medium for theihatching ofveggs'and the warmingV of chicks within' 4the apparatus, thus dispensingfwith thev necessity' of a burners-or heaterl sowtha'tV the apparatus canV be safely used* withinan inclosurersch as ai house orV thel-ike, and the ypresence' of fumes, such asg'as orv odors, `is entirely eliminated,`'a'swell as' thefpossibility-offire.. Y

A vfurtherrolivject of the invention' is the provisionl of an apparatus' of this character wherein the -hotwater ca-ncbe readily. intro# ducedA therein when-the occasion requires and; canJ bei drawn l therefrom withY despatch and the overheating oflthe apparatus -will be auton'iatically avoided.y f

Astill further object ofthe invention is the povision'of an apparatus of this-char.-`

acter which is extremely simplein construe;y tion-,- thoroughly reliable and'. eicientun operation and inexpensive in manufacture.

thif'objxtwill-bein part obvious and in part hereinafter set forth.

the body A, rests 14 uponwhich is` su'per-y impoSedthe egg trayyl, the :samebng readily removable from the compartment' .13, through-' one,- sidei'ofv the 'body A of thejincubator, and inV thisata-y are placed? the :eggs

to behatchedk-i Tlhe"Y tray 15 isfsupported spaced from the bottom 16 of the body'A softhat' the 'space 'below the tray will-*accl'yxn`` 'modat'e the chicks when hatched.

Formed in opposite ends of the body A v are Ventilating openings 17, while slidably mounted in saidends of the bod A are L-f shaped arms 18 which carry venti atordoors g or disks 19 adapted to normally close the openings 17, the doors 19 being locatediexteriorly of the body A and are carried on inturned ends 20 of the arms. 18which latter are connected to an expansible and contrae tible bulb 21 which constitutes a thermostat for controlling the ventilating doors 19and regulated by the rise and fall of temperature interiorly of the body A of the incubator. so as to prevent the overheating of the latter.

In the use of the incubator boiling or hot water is introduced through the pipe 11 into the tank or reservoir 6 and the heat there-v from'serves to create the requisite temperature interiorly of the body A for the hatching of the eggs placed within the tray 15. In event that the temperature rises beyond a predetermined degree the thermostat 21 will automatically operate the Ventilating doors 19 so that the excess heat can escape from the interior of the body A and in this manner the temperature is maintained at apredetermined degree for the successful and proper heating of the eggs and the warming of the chicks within the incubator. Thus it will be seen that the use'of a lamp or burner is entirely dispensed with, thereby eliminating fumes such as gas or odors and also avoiding the possibility of coniagration.

Extending from the horizontal portion of the inlet pipe 11 is a drain cock 22 which permits the water to be drawn from the tank or reservoir 6, the said horizontal portion of the pipe being extended or communicating with the tank or reservoir 6 contiguous to the bottom thereof. The space above the tray within the compartment 13 is the heat space. It will be apparent that hot or boiling water can be introduced into the reservoir or tank 6 at anytime the occasion requires, so as to assure the proper heating temperature within the incubator for the successful operation thereof. By the use of hot water for heating the incubator the health or condition of the chicks when hatched is materially improved to assure life and growth. 'l

From the foregoingdes'cription, taken in` connection with the accompanying drawing, the construction and operation of the herein described incubator will be readily apparent and, therefore, a more extended explanation has been omitted.

Having thus described my invention7 `I claim:

1. Inra device of the class described in combination a rectangular receptacle, means for supporting said receptacle, a series of horizontally disposed strips mounted in said receptacle, a fiat top secured upon said receptacle and having its marginal portion projecting aroundthe same, a sheet metal tank mounted upon said strips and having its sides spaced apart Jfrom the sides of the flushwith the outer face of said top and having a portion projecting intothe airpipe, an L shaped water inlet pipehavinga drain valve at the outer end of its horizontal portion, the inner end of whichhorizontal portion lis connected to the lower end .of said tank, the upper end of the vertical portion of said L-shaped pipe having a flaring portion terminatingin an enlarged dish-shaped portion both of which portions are countersunk within the projecting portion of said top.

2. In a device of the class "described in combination av receptacle, divided into an upper and lower compartment, the lower compartment forming a heating chamber formed upon itsopposite sides, directly below the upper compartment with air openings, alpair of supporting strips secured upon opposite sides of vthe lower compartment andspaced above thel bottom of the-latter, a `tray sup# ported upon said stripsbelow said air openings, a thermostat expandingand contracting element arranged upon the bottom of the lower receptacle, horizontal slidable' rods projecting through the perforated sidesV of the lower compartment and having their inf ner ends secured to said thermostat element, said rods being formed with vertical arms extending alongside of the said receptacle and terminating in inwardly projecting por- K [l tions and a pair of valves secured to said ROBERT F. HUME.

Bogie! of this patent may be obtained for. live-cents each, by addressing the Commissioner of Patentl, Washington, D. (2.
